CULTIVATOR.

Patented April 2, 1907.

Application filed October 22, 1906. Serial No. 339,979.

In the accompanying drawings, Figure is a side elevation of a cultivatorcontaining my im rovements in whichthe beam is partially owered. Fig. 2is a similar elevation in which the beam is elevated. Fig. 3 is aperspective view of forward portion of the cam and its connection withthe axle of a supporting-wheel. Fig. 4 is a erspective view of theconnection of the stu -axle with the main frame. Fig. 5 is a plan'viewof the cultivator in which the seat 1s not shown.

The main frame 1 of the cultivator suports two stub-axles 2 in a pivotalmanner.

bupporting-wheels 3 receive the stub-axles and a seat-frame 4 supports aseat 5.

'An arch-bar 6 isfixedly connected tothe main frame forward of thestub-axles and has laterally-extending portions 7, one for each beam,and as the connection for manipulating the beam and wheel are the samefor both sides of the cultivator a description of one side will answer;but reference-numerals will be applied to both sides.

A brace-rod S connects the portion 7 with the main frame 1.

On the portion 7 of arch-bar 6 is pivotally mounted a sleeve 9,- havinga depending arm 10. A rod 1 1 has one end pivotally connected with, thearm 10, and its other end has a movable connection with the stubaxle 2.The pivotal connection of the rod 11 with the arm 10 is by aninternallyscrewthreaded collar 12, which receives the screwthleaded endof the rod. The collar has a pivotal connection with the arm. Thisscrew-thread connection, permits the collar to be bodily adjusted inconnection with the rod. The movable connection of the rod 11 with thestub-axle 2 is formed by an eye,-

bolt 13, capable of an axle adjustment in connection with the stub-axleand clamped. .in its'adjusted position by the nut 14. The

rear end of the rodill has an eye 15, which engages the eyebolt 13. Byloosening thenut 14 the eyebolt-13 will turn in its connec tion with thestub-axle 2, which will permit the rod 11 to turn in its screw-threadedcon nection with the collar, and by tightening thenut 14 the rod will beheld against axia movement. I The collar 12 can be disengaged from thearm 10 and adjusted alongv the rod and again placed injconnection withthe arm. 7

An evener '16 is 'pivotallyconnected with the main frame in the usualmanner and from the ends depend the draft-bars 17, and

a draft-rod 18c0nnects the draft-bar 17 with the arm 10 of the sleeve 9.

A swingletree 19 has a connection with the draft-bar 17. l.

A beam 20 is intended to be supported at its forward end by each" of thelateral portions of the arch-bar. a

' Around the sleeve 9 is clamped a collar 21 in a manner to move withthe sleeve] To the collar 211's connected the forward end of the beam 20by thetwo-part bracket 22.

In raising or lowering the beam 20 the sleeve will be rocked in itsconnection with the portion 7 of the arch-bar 6; but the connection ofthe beam with thearoh-barpis such that the beam can have theusual'late'ral swinging movement necessary in use.

The beam 20 supports shovels 23-and a foot-rest 24. The main framesupports a toothed segment 25, also a handever 26, provided with theusual dog engagement with the: toothed segment. The flexibleconnection'27 is formed between the handlever and beam. By thisarrangement a connection is formed between the beams andsupporting-wheels, and as the beams are sup ported by the arch-barindependently each beam will controla-supporting-wheel.- The operatorcan shift the position of a supporting-wheel with respect to the mainframe by raising or lowering a beam. This can be accomplished by meansof the hand-lever in its connection with the. beam.

When the shovels are in the ground, the main frame will be balanced-thatis, the weight ofthe operator being in rear of the axle will balancethat part of the structure forward of the axle- S0 that there will be noneck-draft on the team. In' raising the beams and attached shovelsadditional-weight will be thrown onto the horses necks, and this iscounteracted by changing the relative position of the wheel and thepivotal connection of the stud-axle with the ,main frame, as shown atFig. 2.

It has been the custom to provide a separate lever forcounterbalancin'gthe frame the main frame and capable of a bodily move-vment in the direction of the line of draft, two shovel-sup ortingbeamsindependently connected to tfie main frame and capable of independentvertical movement, means for raising and lowering the beamsindependently,

and connections whereby the said' means move a supporting-wheel.

2. In a cultivator, a main fra'me,: two sup-- the main frame and capableof a bodily movement in the direction of the line of draft, two shovelsupporting beams independently con nected to the main frame and capableof independent vertical movement, and means for moving the supportingWheel and beam of one side of'the main frame in unison and independentlyof the su porting wheel andbeamof theother' side of t e main frame.
